What is the naming process of alkanes, alkenes, and alkynes
Answer: Heyo Kenji Here! Here's your answer- Higher alkenes and alkynes are named by counting the number of carbons in the longest continuous chain that includes the double or triple bond and appending an -ene (alkene) or -yne (alkyne) suffix to the stem name of the unbranched alkane having that number of carbons.
Explanation: Hope this helps!
Have a nice day!

The solubility of a gas is 0.980 at a pressure of 116 kPa. What is the solubility of the gas if the pressure is decreased to 101 kPa, given that the temperature is held constant
The solubility of the gas when the pressure is decreased to 101 KPa at constant temperature is 0.853
Henry's lawThis states that the solubility of a gas in liquids at constant temperature is proportional to its pressure. Mathematically, it can be expressed as
S₁ / P₁ = S₂ / P₂
Where
S₁ is the initial solubility P₁ is the initial pressure S₂ is the new solubility P₂ is the new pressure How to determine the new solubilityFrom the question given above, the following data were obtained
Initial solubility (S₁) = 0.980Initial pressure (P₁) = 116 KPa New pressure (P₂) = 101 KPaNew solubility (S₂) =?S₁ / P₁ = S₂ / P₂
0.98 / 116 = S₂ / 101
Cross multiply
116 × S₂ = 0.98 × 101
Divide both side by 116
S₂ = (0.98 × 101) / 116
S₂ = 0.853

Determine the pressure change when a constant volume of gas at 0.850 atm is heated from 20.0C to 30.0C
Answer:
0.425 atm
Explanation:
According to Ideal Gas Equation,
PV = nRTTherefore, P ∝ TP₁T₂ = P₂T₁Given :
P₁ = 0.850 atmT₁ = 20.0 CT₂ = 30.0 CSolving :
0.85 x 30 = P₂ x 2030 x 17/20 = P₂ x 20510 = 400P₂P₂ = 510/400 = 1.275 atmChange in pressure = ΔP = P₂ - P₁ = 1.275 - 0.850 = 0.425 atmIf two reactant particles collide, but bounce away unaffected, this is called a(n).
a)ineffective collision
b)effective collision
C)nonspecific collision
d)rearrangement of atoms
If two reactant particles collide, but bounce away unaffected, this is called an ineffective collision.
The Collision theoryAccording to the collsion theory, the reaction between particles occur as a result of the collsion of particles that have energy that is in excess of the activation energy.
Now if two particles, do not posses the activation energy, they collide and rebound from each other. This is called an ineffective collision.

Answer:
4.7 Liters of NO2
Explanation:
mole weight of HNO3 (from periodic table) = ~~ 63 gm/mole
12 grams of this is 12/63 = .19047 mole
From the equation, you should be able to see that 3 moles of NO2 produces 2 moles of HNO3
so you need 3/2 * moles HNO3 = .2857 moles of NO2 needed
PV = nR T n = moles R = .082057 L-atm/(k-mole) 25 C = 298.15 K
1.6 (V) = .2857 (.082057)(298.15)

Considering the Avogadro's Law, 1.52 moles are left in the container.
Avogadro's LawAvogadro's Law is a gas law that establishes the relationship between the amount of gas and its volume when temperature and pressure are held constant.
This law states that the volume is directly proportional to the amount of gas: if the amount of gas increases, the volume will increase; while if the amount of gas decreases, the volume decreases.
Mathematically the law can be expressed as:
[tex]\frac{V}{n}=k[/tex]
Assuming that you have a certain amount of gas n1 that occupies a volume V1 and the amount of gas varies until a new value n2, then the volume will change to V2, and the following will be true:
[tex]\frac{V1}{n1}=\frac{V2}{n2}[/tex]
Amount of moles left in this caseIn this case, you know:
V1= 65 Ln1= 2 molesV2= 49.4 Ln2= ?Replacing in the Avogadro's Law:
[tex]\frac{65 L}{2 moles}=\frac{49.4 L}{n2}[/tex]
Solving:
[tex]n2x\frac{65 L}{2 moles}=49.4 L[/tex]
[tex]n2=\frac{49.4 L}{\frac{65 L}{2 moles}}[/tex]
n2= 1.52 moles
Finally, 1.52 moles are left in the container.

How many carbon atoms does one molecule of pyruvate contain?.
Hi!one molecule of pyruvate contains three carbon atoms.
Glycolysis produces two pyruvate molecule and there are three carbon atoms are present in each pyruvate molecule.
What is glycolysis ?Glycolysis is the process in which glucose is broken down to produce energy. It produces two molecules of pyruvate, ATP, NADH and water. The process takes place in the cytoplasm of a cell and does not require oxygen. It occurs in both aerobic and anaerobic organisms.
There are two pyruvate molecules produced at the end of glycolysis for every molecule of glucose metabolized. Therefore, two of the six original carbons will have been eliminated as CO2 at the end of this step.
The main purpose of glycolysis is to provide pyruvate for the trichloroacetic acid (TCA) cycle, not to make adenosine 5′-triphosphate.
Thus, there are three carbon atoms are present in pyruvate compound.

Suppose you heat 4.24 g of S8 with 5.00 of Cl2, what would be the theoretical yield of S2Cl2? If the actual yield of S2Cl2 is 6.55g, what is the percent yield
S8 (l) + 4Cl2 (g) ------> 4S2Cl2 (l)
Answer:
Explanation:
Part 1: Theoretical yield
5.00 + 4.24 = 9.24 grams
Part 2: Percent yield
Percent yield = (actual yield)/(theoretical yield) * 100 = (6.55)/(9.24) * 100 = 70.9%

The percent yield of oxygen if 10.2 g of O₂ is produced from the decomposition of 17.0 g of H₂O is 67.6%.
How do we calculate moles from mass?Moles (n) of any substance can be calculated by using their mass as:
n = W/M, where
W = given mass
M = molar mass
Given chemical reaction is:
2H₂O → 2H₂ + O₂
Moles of 17g H₂O = 17g / 18.02 g/mol = 0.943 moles
From the stoichiometry of the reaction it is clear that,
2 moles of H₂O = produces 1 mole of O₂
0.943 moles of H₂O = produces 1/2×0.943=0.471 mole of O₂
Now mass of this 0.471 moles of O₂ = (0.472mol)(32g/mol) = 15.104 grams
Actual mass of oxygen = 10.2g (given)
Now on putting vales on the percent yield formula, we get
% yield = (10.2 / 15.104)×100% = 67.53% = 67.6%
Hence the required value of percent yield is 67.6%.

Particle theory states that particles are attracted to each other??
True or false
Answer:
true
Explanation:
Students often have no experience with the idea that some things (particles) can’t be divided. If sand is ground up into tiny pieces it is still sand. There seems no reason why the dividing can’t keep on going to smaller and smaller pieces. This is often described as a continuous view of matter.
Even when children are introduced to the idea of matter being made of particles, most consider there is still ‘stuff’ between the particles and that something like air fills the empty space. After all, when liquid is poured from a glass so that it is empty it still contains air.
These ideas are further explored in ‘Hannah’s Question,’ a classroom practice vignette.
Research: Loughran, Berry, Mulhall & Gunstone (2001), Novick & Nussbaum (1981)
Particles are often assumed to behave in the same way as the substances they make up. For example students can believe that particles themselves can swell, shrink and melt or that the particles in stone are harder than the particles in rubber. Many students consider that ice molecules melt to little droplets of water.
Scientific view
The properties of matter can best be explained using a model in which all materials are composed of tiny particles (atoms, molecules and ions).
There is empty space between particles and particles are constantly moving (their speed is changed by temperature). The particles in solids and liquids are quite close to each other, while those in gases are a very long way apart. (There is commonly an increase in volume of at least 1000 fold when substances move from solid or liquid to gas).
Changes of state involving solids, liquids and gases as well as a range of other phenomena can be explained by changes in arrangement and speed of the particles.

How many moles of nitrogen gas are in 2.00 L of N2 gas at STP
The number of mole of nitrogen gas in the 16.8 L container is 0.75 mole
Data obtained from the question
Volume (V) = 16.8 L
Pressure (P) = STP = 1 atm
Temperature (T) = STP = 273 K
Gas constant (R) = 0.0821 atm.L/Kmol
Number of mole (n) =?
How to determine the number of mole
The number of mole of the nitrogen gas can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
Divide both side by RT
n = PV / RT
n = (1 × 16.8) / (0.0821 × 273)
n = 0.75 mole
Thus, the number of mole of the gas present is 0.75 mole

Answer: 11.478
Explanation:
M = MBVB- MAVA/VA + VB
= number of moles of base - number of moles of acid/total volume
= 3.6*10^-3 - 5.95*10^-4/1
= 0.0036-0.000595 = 0.003005
[OH^-] = M = 0.003005M
POH = -log[OH^-]
= -log0.003005
= 2.522
PH = 14 - POH
= 14 - 2.522
= 11.478
Therefore, the pH of the solution is 11.478
